Description

The invention relates to a rail vehicle with a cladding arrangement for cladding an interior of the rail vehicle in the area of ​​a functional carrier, comprising a first cladding element, fastening means for attaching the first cladding element to a body structure and a recess in the first cladding element for passing through or receiving the functional carrier. A panel arrangement of the type described above is shown, for example, in DE 196 06 792 A1. Lighting and sound elements are integrated into the ceiling paneling, flush with the surface. Such paneling must be regularly opened or removed for maintenance and repairs on a rail vehicle. Previously, functional components were integrated into the movable or removable ceiling and connected to the car body's structural frame via flexible lines, such as hoses or cables. If the ceiling paneling is removed, for example for maintenance or installation work, the lighting and sound systems typically remain in place, with any connected cables being long enough to allow for movement of the paneling. Therefore, if the ceiling paneling is completely removed, the lines must be disconnected and, if necessary, reconnected before the paneling is reinstalled. One problem with known cladding arrangements of the type mentioned above is that the assembly of the cladding arrangement and the functional components used within it is relatively complex. The cables connected to a functional component must be long enough to allow the cladding elements to be detached without completely disassembling the functional component. However, the movement of these cables can lead to fatigue and damage. The object of the present invention is therefore to provide a cladding arrangement for a functional component in a rail vehicle that is easy to assemble. A further object is to reduce the wear and tear occurring on the connections and lines of functional components during the assembly and disassembly of the cladding arrangement. This problem is solved with a rail vehicle having a fairing arrangement according to claim 1. According to the invention, the fairing arrangement comprises a second fairing element, a recess in the second fairing element for receiving the functional carrier, and fastening means for attaching the second fairing element to the functional carrier. The second fairing element is configured to overlap the recess in the first fairing element at its edges when the fairing arrangement is assembled. The second fairing element, which serves in particular to fair the functional carrier, can therefore be pre-assembled independently of the first fairing element, especially in front of the first fairing element. Further embodiments, modifications and improvements are described below and the attached claims are included. The trim panels serve to cover and protect the vehicle's structural components, lines, and other functional elements. Accordingly, the trim panels can preferably be flat or plate-like. When the trim assembly is installed, the second trim panel is partially concealed by the first. After the first trim element is installed, the first and second trim elements can interact as a trim assembly. Transitions between the first and second trim elements, i.e., overlapping areas of the two trim elements, can together form a trim panel that appears closed, at least from a passenger's perspective. To completely cover the recess of the first trim element, the second trim element preferably has an extension that extends beyond the recess of the first trim element along its entire circumference. The cladding arrangement according to the invention is particularly suitable for applications in the ceiling area, where often the majority of connecting lines and corresponding functional carriers of a rail vehicle are located and passengers do not usually exert forces on the cladding. According to a preferred embodiment of the invention, the first cladding element can be pivotably designed, wherein the recess is configured such that the first cladding element can move past a functional carrier extending through the recess in the assembled state of the cladding arrangement. The recess in the first cladding element can be configured to be large enough that the cladding element can be pivoted over a functional carrier received or inserted into the recess without the functional carrier touching the cladding element during the pivoting process. Correspondingly, the second cladding element can be configured to be larger than the recess in the first cladding element, so that the recess is completely covered, at least in the assembled state of the cladding arrangement. In a further advantageous embodiment of the invention, fastening elements are provided on the second cladding element for the repeatedly detachable fastening of the first cladding element. Thus, the first cladding element can be connected to the second cladding element, and a more uniform distribution of fastening points can be achieved. In a rail vehicle with a fairing device according to the invention, the functional element projects into the passenger compartment when the fairing assembly is installed. The functional element can, for example, comprise an arrangement of spray nozzles for fighting fires or lighting elements. An exposed position in the passenger compartment thus improves the efficiency of the functional element. The first paneling element can preferably be pivotally attached to the car body. For this purpose, the first paneling element can be attached to the car body or the adjacent paneling via a hinge. Accordingly, the recess in the first paneling element can be designed such that the first paneling element can be moved past the functional carrier, which extends into the passenger compartment through the recess when the paneling assembly is mounted, at least partially. Preferably, the recess in the first paneling element is designed such that the first paneling element can be moved or pivoted completely past the functional carrier. Preferably, the first paneling element can be pivoted or moved past the functional carrier without touching it.The recess in the first cladding element can, in principle, be chosen to be of any size, because the remaining opening is covered by the first cladding element in the assembled state or operating state of the cladding arrangement. In a further advantageous embodiment of the invention, the recess of the first cladding element substantially completely surrounds the functional carrier, with the second cladding element being arranged substantially centrally above the recess and overlapping it at the edges. The first cladding element can form a closed surface surrounding the functional carrier. Similarly, the second cladding element can also form a closed surface surrounding the functional carrier. The second cladding element preferably overlaps the first cladding element over the entire circumference of the recess provided for the functional carrier. Preferably, the second cladding element is attached to the functional carrier. The second cladding element can, in particular, be rigidly connected to the functional carrier. This allows the second cladding element to be optimally adapted to or aligned with the functional carrier without its position relative to the functional carrier changing when the first cladding element is opened. The functional unit can ideally be attached to the car body via a bracket or directly. This results in a largely rigid arrangement of the functional unit, which prevents unintentional movement and damage to the lines leading to the functional unit. Ideally, when the cladding assembly is installed, the attachment point of the functional component, which connects it to the second paneling element and / or the car body, is located between the car body shell and the cladding assembly. Thus, from the passenger compartment, the attachment points are concealed by the cladding. Furthermore, according to a preferred embodiment, the functional element can be connected via rigid lines. In particular, a functional element serving as a spray nozzle for a fire suppression system can be supplied with a fire suppressant via essentially rigid pipes instead of hoses. The invention is directed in particular to functional elements that are connected via supply lines. According to the invention, the functional element can be, in particular, a spray device for a fire suppression system, a lighting device, or a sound system. Because, with the solution according to the invention, the functional element and the supply lines connected to the functional element, i.e., power or fluid lines, can remain in place even when the cladding is repeatedly opened, the supply lines can also be rigidly connected to the car body. To prevent relative movement between the first and second cladding elements of the cladding assembly during operation of the rail vehicle, and thus to prevent the formation of noise and wear, the first and second cladding elements can be spaced apart. A gap can be provided between the first and second cladding elements to prevent contact between them. In a further preferred embodiment, the first and second cladding elements can abut each other. This allows the first and second cladding elements to support each other, enabling thinner materials and preventing noise caused by any movement of the cladding elements. The first and second trim elements are preferably made of the same material, in particular with the same surface finish, to ensure a uniform appearance for the trim assembly. Ideally, the color or pattern on the side of the trim elements facing the passenger compartment is also identical. In a method for assembling a rail vehicle according to the invention, the following steps are provided: First, a functional carrier is attached to the body shell of the rail vehicle, wherein the functional carrier can be attached directly or via a bracket to the body shell. The second trim panel is then mounted onto the functional carrier. Ideally, the second trim panel is attached directly to the functional carrier. To do this, the functional carrier is first inserted into the recess in the trim panel until the trim panel is positioned correctly. In the next step, the trim panel can be rigidly connected to the functional carrier. Finally, the first trim element is installed. If the trim assembly is mounted on a vehicle ceiling, the first trim element is slid or pivoted from below onto the second trim element and the functional carrier. A method for assembling the cladding device comprises the following steps: attaching a second cladding element to a functional carrier or adjacent to the functional carrier of the rail vehicle, aligning a recess of a first cladding element parallel to the second cladding element, fixing the first cladding element. A preferred embodiment of the cladding device according to the invention is described below with reference to Figures 1, 2 to 3. Figure 1 is a sectional side view of a cladding arrangement according to the invention in its assembled state or in an operating position; Figure 2 is another sectional side view of a cladding arrangement according to the invention with the cladding element open; Figure 3 is a top view of a cladding arrangement according to the invention. Fig. 1 shows a cladding arrangement 1 according to the invention, located in the car body of a rail vehicle, in its assembled state and in its operating state. The cladding arrangement 1 forms a ceiling cladding of a rail vehicle, which is in a closed state. The cladding arrangement 1 is located below and attached to the body shell 2 of a car body. The cladding assembly 1 comprises a first cladding element 3 and a second cladding element 4. The first cladding element 3 is provided with fasteners 5 for attachment to the body structure 2. The fasteners, shown here as mounting brackets, can alternatively be screws, connectors, or other detachable fasteners. The cladding assembly 1 is located in the area of ​​a functional carrier 6. The functional carrier 6 is part of a fire suppression system that combats fires in the event of a fire on the rail vehicle. In this embodiment, the functional carrier 6 comprises a spray head 13 equipped with spray nozzles 7 to transport and distribute an extinguishing agent towards the source of the fire in the event of a fire below the functional carrier 6. The extinguishing agent is transported to the functional carrier 6 and to the spray nozzles 7 via a line 8 connected to the functional carrier 6. Below the functional unit 6, and thus within its effective range, is a passenger compartment 9. For optimal efficiency of the functional unit 6, it is important that the functional unit 6 is positioned prominently within the passenger compartment 9, because only in this way can the spray nozzles 7 arranged laterally on the functional unit 6 fully exert their effect. For this reason, the functional unit 6 projects into the passenger compartment 9. The second cladding element 4 is arranged directly on the functional carrier 6 and is provided with a recess into which the functional carrier 6 is inserted. The recess in the second cladding element 4 thus serves as a fastening means for attaching the second cladding element 4 to the functional carrier 6. The functional carrier 6 itself is connected to the body structure 2 via a fastening element 10. The fastening element 10 can be designed as a bent sheet metal part, with the functional carrier 6 being inserted into a receiving opening 11 of the fastening element 10. The fastening element 10 is screwed directly to the body structure 2 by means of a screw connection (not shown here). All fastening points of the functional carrier 6 are therefore located between the body structure 2 and the cladding assembly 1. Thus, there is an essentially rigid connection between the functional carrier 6 and the structural frame 2. This prevents the line 8, which is also essentially rigidly connected to the spray head 13, from absorbing forces acting on the spray head 13. Instead, the spray head 13 remains in its position, regardless of the assembly status of the first cladding element 3. To secure the functional carrier 6 in the receiving opening 11, it is provided with a thread 12 that is screwed directly into a corresponding thread of the fastening element 10. Alternatively, other fastening elements are also conceivable at this point, for example screws, in order to connect the functional carrier 6 to the fastening element 10 without requiring a rotational movement of the spray head 13. The second cladding element 4 is located directly above the spray head 13 and connected to the functional carrier 6. The second cladding element 4 is also fixed to the structural frame 2 via its attachment to the functional carrier 6. The functional carrier 6 is inserted into a recess 14 of the first cladding element 3. The diameter of the essentially round recess 14 is significantly larger than the diameter of the spray head 13. The size of the recess 14 allows the first cladding element 3 to pivot downwards in an opening direction 15 without colliding with the spray head 13. To enable the cladding element 3 to pivot downwards, the cladding assembly 1 includes a hinged connection 16. On the side opposite the hinged connection 16, the first cladding element 3 is locked in place by a latch (not shown). To form a closed cover assembly 1, the second cover element 4 overlaps the recess 14. The second cover element 4 rests on the back of the spray head 13, leaving a gap 17 between the second cover element 4 and the first cover element 3. The gap 17 prevents contact between the first cover element 3 and the second cover element 4, thus preventing contact and rattling between the cover elements 3 and 4, even during shocks or vibrations while driving. Furthermore, the gap 17 compensates for assembly tolerances, and slight changes in the distance between the cover elements 3 and 4 do not affect their function. As an alternative to gap 17, it is conceivable that the first cladding element 3 and the second cladding element 4 rest against each other. In this embodiment, a preload is provided between the cladding elements 3 and 4, which prevents relative movement between them and serves to compensate for tolerances. Figure 2 shows the cladding assembly 1, located in a car body, in an open position. When the first cladding element 3 is pivoted about the articulated connection 16, an opening 18 is created. Through this opening 18, access to the functional carrier 6 or other functional elements located between the cladding assembly 1 and the car body's structural frame 2 can be gained during assembly or maintenance work. These functional elements could include, for example, cables, light sources, loudspeakers, or fasteners. Regardless of the position of the first cladding element 4, the position of the functional carrier 6 and the second cladding element 4 remains unchanged. This makes it possible to use rigid, solid cables 8 for connecting the functional carrier 6 and simultaneously allows for repeated opening of the cladding assembly 1 without having to move or disconnect the cables 8. The cables 8 are preferably fixed within the car body, but can be flexibly connected to the car body at the transition to the body shell 2 to allow for tolerance compensation with respect to the fastening of the functional carrier 6. Due to the relatively large diameter of the recess 14 of the first cladding element 3, its movement when the cladding assembly 1 is opened is not restricted. At any opening angle in the opening direction 15, the first cladding element 3 remains spaced away from the functional carrier 6. Fig. 3 shows the embodiment of the panel arrangement 1 according to the invention from the perspective of a passenger, i.e., from the outside or from below. The first panel element 3 is in a closed position and is arranged below the second panel element 4 at the distance of the gap 17 shown in Fig. 1. The first panel element 3 is held on the left side by the hinged connection 16 and connected to the adjacent panel on the right side by a locking mechanism (not shown here). The functional carrier 6 is arranged centrally in the recess 14 of the first cladding element 3. In this embodiment, the functional carrier 6 has a substantially round cross-section and an outer diameter 20 that is significantly smaller than the inner diameter 21 of the recess 14. This prevents contact between the functional carrier 6 and the first cladding element 3 during pivoting about the hinged connection 16. The second trim element 4 has an outer diameter 22, which is significantly smaller than the inner diameter 21 of the recess 14. Thus, the second trim element 4 is covered by the first trim element 3 in the area of ​​its outer diameter 22, creating an overlap between the outer diameter 22 of the second trim element 4 and the first trim element 3, which completely covers the gap 17 between the trim elements 3 and 4 from the perspective of the passenger compartment 9. To accommodate the functional carrier 6, a recess 23 is provided in the second cladding element 4, into which the functional carrier 6 is inserted. The recess 23 also serves to fix the second cladding element 4 to the structural frame 2. The second cladding element 4 is not attached to the functional carrier 6 by any other fasteners. The specific embodiments described and illustrated are not binding for the implementation of the invention, but can be suitably modified within the scope of the present invention without deviating from the scope of protection of the present invention.
